Frequency/Digital outputs 53
Output for FODO1 and Digital Output1 (Group 1 on the CPU Module) share a common ground
and have 50V isolation. FODO2 and FODO3 (Group 2 on the CPU Module) share a common
ground and have 50V isolation. This allows an output to be connected to a different flow
computer. The outputs are opto-osculated from the CPU Module and have a withstand voltage
of at least 500V rms dielectric.
